摘　　要：针对聚硫橡胶废水的水质特性,分析探讨了采用厌氧生物处理法处理该废水的可行性以及在不同浓度下厌氧生物法的处理效果。试验结果表明,常温下,废水COD为2500mg/L时,COD去除率达到88.7%,当COD>10000mg/L时,相应的COD去除率较低且较为接近。该废水有较强的缓冲能力,水解的最佳时间为4h,脱色率达到70.2%。The anaerobic biological treatment has been used for treating thickol wastewater. The effect of the anaerobic biological treatment on influent wastewater with different concentration has been analyzed. The results show that the COD removal rate reaches 88.7% when the wastewater COD is 2 500 mg/L.When the COD are above 10 000 mg/L,the COD removal rates are lower and similar. The thickol wastewater has stronger buffering capacity and the best hydrolyzed time is 4 h. The best decolorization rate is 70.2%.
